Discovering a VS UUID Characterisic, but it shows UUID as 0

Dresse

Hi,

I am running SDK15, and using the example ble_app_interactive in ble_central and peripheral. I am trying to discover services and characteristic from a peripheral device, using NRF52 DK as a central device. There is a lot of services and VS services and characteristic in the peripheral. I can discover the services, and see the VS UUID services. As seen on picture:

But when i try to discover the characteristics in the VS services, it writes out the UUID as 0. I have also made it print out it handles and it does have it's handles Both things is shown in pictures below.

The UUID is 0. This is by using gatt characteristics <address> 2EAF.

If i then try to write gatt characteristics <address> AE62. I still don't get UUID, but my progam also crashes and gives me error code 11, but this is in the CCCD descriptor, as seen on picture:

I have made extra logging. I have also increased NRF_SDH_BLE_VS_UUID_COUNT in sdk_config. I have also increased my maximum characterstics and services. Hope you can help.

Regards Andreas

    Hi Dresse, 

    Please post a full log of your test, including the commands you type in. I don't see the part where you find the VS services I would suggest you also test first with connecting to ble_app_uart, just to test if it would work with a simple custom profile.

    Alright, I now have the full log. I have added some extra text to the program, so I know where it is, hope you can see past that. The first log file, show the communation between the hearingaid, and the Nordic.

    I also did a test where I try to connect, to my phone, and setting up my GATT server on my phone with a custom service UUID, and custom characteristic UUID. And that worked perfectly:

    I think it has to do with some settings in the config file or where ever. The hearing aid have 5 custom VS UUID services and quite a few VS UUID characteristics. I have already turned up NRF_SDH_BLE_VS_UUID_COUNT, but perhaps I have to turn another setting up?

    And another thing, if I connect to the hearingaid using my phone, and using nrf connect, I get all services and characteristics, so the hearingaids works just fine.
